Objective To study the epidemiological and clinical characteristics of patients with severe acute respiratory syndrome(SARA). Methods Clinical data from 682 patients with SARS were retrospectively analyzed. Results The patients ranged from 13 to 76 years old, 387 male and 295 female. A total of 356 patients (52.2) had a history of close contact with diagnosed SARS patients, and 113 (25.1%) had been to hospital ever. The most common symptom was fever (99.3%), followed by cough (44.4%), shortness of breath (12.2% ), diarrhea (8.9%). 596 patients (87.4%) had normal or decreased white blood cell counts. Serum ALT and CPK levels were elevated in 112 patients (16.4%)and 17 patients (2.5%) respectively. Infiltrates on chest radiography were seen in all patients, with 69.8% involved both lungs. Six patients (0.9%) died of SARS. Conclusion SARS is infectious. Hospital is an important place where SARS transmits. Fever, cough and infiltrative changes on chest radiography are mainly symptoms and signs.

AIM: To investigate the effect of intraventricular pressure change by volume overload (VOL) on expression of proto-oncogene c- fos ,c- jun ,c- myc and egr-1 . METHODS: Left ventricular systolic pressure(LVSP) and left ventricular end diastolic pressure (LVEDP) of rat with VOL induced by aortacaval fistula operation and rats of control group were measured at 30 min, 1, 4, 6, 12 and 48 h after the operation,these mRNAs at the foregoing time points were measured by slot bloting method and quantified with densitometry. RESULTS: Be compared with the control group, VOL rats LVSP decreased ( P 0.05) after the operation.The proto-oncogene expression signals were not detected in the control,negative controls and VOL rats at 30 min after the operation. The c- fos, c- jun and egr-1 mRNA signals appeared earlier,at 1 h, and c- myc mRNA increased later at 4 h.All reached peak value at 4 h and then declined gradually.The c- fos mRNA were not detected at 48 h. The c- myc ,c- 0jun and egr-1 mRNA persisted throught the entire observation period from 1 h to 48 h. CONCLUSIONS: During VOL early phase the overload have effect on expression of the proto-oncogene mRNA,c- fos, c- jun and egr-1 mRNA appear earlier, c- myc later, egr -1,c- jun and c- myc persist longer period, but the expressions do not strengthen with the ventricule wall load increase.This sequential induction pattern may reflect the time course regularity of the proto-oncogenes expression induced by VOL,and indicate the proto-oncogenes expression initiate while the heart load accumulate some extent and duration and the load magnitude may not play a critical role.

To analyze the reasons of injuries during surgical practices and explore the hazards and the corresponding preventive measures. The surgical interns don't receive enough training of injury prevention. They don't pay enough attention to the occupational prevention and are not skilled in operation, which causes high rate of sharp edged instrument injuries. Therefore, a perfect plan of education, training and treatment must be made to reduce the occupational injuries and blood sourced diseases.

AIM: To determine the alterations of myocardial ? 1-adrenergic receptor (? 1-AR) and cardiac sympathetic norepinephrine transporter (NET) mRNA expression, which is upstream modulator of ? 1-AR, in rats with longterm volume overload (VOL).METHODS: Left ventricular systolic (LVSP) and end diastolic pressure (LVEDP) of rats with VOL induced by aortacaval fistula operation and control group were measured at 3, 14,30 and 60 d after the operation, the mRNA at the time points was measured by RT-PCR and Northern blot analysis and quantified by densitometry.RESULTS: The cardiac sympathetic NET specific expression is in the cardiac sympathetic ganglia. Be compared with the control group, LVSP of VOL rats decreased most dramatically by 24%( P

Objective To study the relationship between chromosomal abnormality and Y chromosome microdeletions and male infertility. Methods Lymphocytes were cultured from peripheral blood of 1975 male infertility patients and stained with Giemsa. The chromosomes were analyzed under microscope. Y chromosome specific sequence tags (STS) were selected, then the Y chromosome microdeletions in AZF regions were screened by polymerase chain reaction (PCR) in azoospermia and oligozoospermia patients. Results There were 305 cases of detected chromosomal abnormalities (15.44%) in the 1975 cases. There were 101 cases (5.11 %) with autosome abnormalities which clinically manifested as oligozoospermia and teratospermia. There were 204 cases (10. 33%) of sexual chromosome abnormalities and the patients were mainly characterized with Klinefelter's syndrome. Y chromosome microdeletions were detected in 109 (14.97 %) of the 728 cases of azoospermia or oligozoospermia. The most common microdeletion of Y chromosome was AZFc (62.39%) and these patients were characterized with azoospermia and oligozoospermia. Five patients (4. 59%) who suffered Y chromosome microdeletion in AZFa region and AZFb region were characterized with azoospermia. Fifteen cases (13.76%) with microdeletion in AZFb region and AZFc region were mainly characterized with azoospermia. There were 6 cases (5. 50 % ) of microdeletion in AZFa, AZFb and AZFc regions,these patients were all characterized with azoospermia. Conclusions Both Chromosome abnormalities and Y chromosome microdeletions are important causes for male infertility.

In the fast pace of modern life and under the heavy work pressure, the prevalence of depression has increased year by year. Meanwhile, the demands for antidepressant drugs have also grown, especially the high-efficiency and low-toxicity natural antidepressant drugs, mainly including polyphenols, flavonoids, organic acids, alkaloids and terpenoids. Cytochrome P450 (CYP450) is a type of enzymes involving oxidative metabolism of drugs in vivo, and can change the pharmacokinetics and efficacy of drugs. Therefore, it is of important significant to define the effect of natural antidepressant drugs on CYP450 in human bodies, in order to improve the rational clinical medication, avoid drug interactions and reduce adverse reactions.

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

OBJECTIVETo investigate the normal occlusal force distribution and the characteristics of the occlusion time at different occlusion position using T-Scan III occlusal analysis system.

METHODSFifty-three volunteers with normal occlusion, including 29 males and 24 females, were included in this study. The average age was (25.9 ± 2.1) years old. T-Scan III occlusal analysis system was used to measure the occlusal force distribution and the time character of normal occlusion at intercuspal position, protrusive position, and lateral excursive position.

RESULTSAt intercuspal position the left and right side molar teeth took the most part of force percentage, followed by (13.3 ± 4.3)%, (13.6 ± 5.4)%, (15.7 ± 7.1)%, (18.7 ± 7.5)% (6, 6, 7, 7); and 7654, 4567 took (61.3 ± 12.4)% force percentage; and the left and right sides took the respective percentages of (46.4 ± 7.0)%, (53.6 ± 7.0)%, the left side was significantly less than the right side(P < 0.05). At the protrusion position the region ( 21, 12) commitment to take the percentage of (85.1 ± 25.5)%. At left and right lateral position, 28% (13/46) and 30%(14/46) were cuspid-protected occlusion, and 33%(15/46) and 44%(20/46) were group functional occlusion, and 39%(18/46) and 26%(12/46) were multiple-protected occlusion. The average occlusion time was (0.34 ± 0.11) s, and disclusion time was (1.00 ± 0.39) s.

CONCLUSIONSAt intercuspal position the region from first premolar to second molar teeth were the occlusal force centers, and the second molar is the most;.the force concentrated in the area ( 21, 12) at the protrusion position. The lateral occlusal pattern is multiformity.
